your value isn't set by your own standards - your value is what someone else will pay you for your time! I.e., the opportunity cost of leisure is the value of leisure.
It's more complex than that. People on salary earn a fixed amount per month - they don't get paid extra if they work an hour longer in the evening instead of shopping. People on most hourly jobs have their schedule set by their manager. They can't pick up an extra hour of work unless their manager has some to offer, and not at the time of their own choosing.

If you define leisure time as the time not spent in paid employment, the opportunity cost of leisure time is actually very high, since each of us has many unpaid tasks that we must do to keep our lives going (such as keeping the living space tidy, stocking the fridge with food, obtaining clothing, etc.)

I think a more accurate way to look at it is that most of us have paid labor (hourly or salaried) and a lot of unpaid labor that we need to do to keep our lives in order. Things like chores, maintenance of our living space, etc.
Leisure time is actually what is left only after we've done all of the paid labor our job demands AND all of this unpaid labor.
For some people, this leaves very little leisure time, but it may leave some extra money that can be allocated to hiring out some of those unpaid tasks in exchange for more time available to do whatever else.
